Plate filter with high odor and toxin removing and water absorbing capacity and its manufacturing processes

Abstract

A plate fiber with high odor and toxin removing and water absorbing capacity and its manufacturing processes includes a catalyzer I such as hydrochloric acid, a catalyzer II such as formalin, a vegetable starch, PVA, and active carbon. The materials are orderly processed through mixing, stirring and being coated on a plate fiber. Then the plate fiber passes through a foaming step, an acid removing step, a cooling step, a washing and compressing step, a drying step, becoming a plate filter washable and able to remove odor and toxin sufficiently and absorb water.

What is claimed is: 
     
       1. Manufacturing processes for a plate filter with high odor and toxin removing and water absorbing capacity, comprising: a material preparing step wherein PVA is mixed with water, heated and stirred at the same time, making it in a non-particle condition, and then cooled down a vegetable starch is mixed with water, heated and stirred at the same time until it becomes starch paste and then cooled down; catalyzers I and II for assisting chemical reaction, active carbon and plate fiber are prepared, wherein said catalyzer I is hydrochloric acid and said catalyzer II is formalin;   a stirring and mixing procedure wherein said cooled starch paste is mixed and stirred sufficiently with said catalyzer I to become a first material solution; said first material solution is then mixed with said PVA to become a second material solution; said second material solution is then mixed and stirred sufficiently with catalyzer II to become a third saturated material solution; said third saturated material solution is then finally mixed with active carbon to become a fourth material solution;   a coating step wherein said fourth material solution is coated on said plate fiber;   a foaming step wherein said plate fiber coated with said fourth material solution is placed in a reaction furnace, which has temperature adjustable for different demanding for foaming, a length adjustable and foaming speed also adjustable according to different demand, wherein said foaming step causes the formation of percolating holes through said plate fiber;   a cooling step wherein said plate fiber having finished said foaming step is cooled down to a room temperature;   a washing and compressing step wherein said plate fiber having finished said cooling step is washed to neutralize said plate fiber into a neutralized condition, and then compressed to remove water and said catalyzers I and II still remaining in said percolating holes of said plate fiber; and,   a drying step wherein said plate fiber having finished washing and compressing steps is dried to become a completely finished plate fiber with excellent stability and with high odor and toxin removing and water absorbing capacity; and said manufacturing process is carried out with the proviso that a foaming agent is added in said preparing material steps in proportion of 0.015-0.06 percent to the aggregate weight of said materials.   
     
     
       2. The manufacturing processes for a plate fiber with high odor and toxin removing and water absorbing capacity as claimed in claim 1, wherein foaming temperature required in said foaming step is 60-200° C., and foaming time required is 10 minutes to 10 hours. 
     
     
       3. The manufacturing processes for a plate filter with high odor and toxin removing and water absorbing capacity as claimed in claim 1, wherein said coating step is carried out by coating said saturated solution on said plate fiber conveyed continuously, and said plate fiber may have any thickness according to necessity. 
     
     
       4. The manufacturing processes for a plate fiber with high odor and toxin removing and water absorbing capacity as claimed in claim 1, wherein an acid removing step is further used after said foaming step, adding a neutralizing agent to neutralize said plate fiber still having a little acid remaining therein. 
     
     
       5. The method of claim 1 wherein said foaming agent is a mixture consisting of p-toluene sulfonate and alkyl fulfonate. 
     
     
       6. The plate filter obtained by the method of claim 5. 
     
     
       7. The plate filter obtained by the method of claim 1. 
     
     
       8. A plate filter with high odor and toxin removing and water adsorbing capacity comprising a catalyzer II in a proportion of 3.6-10.0 percent by weight. a catalyzer I in a proportion of 4.5-10 percent by weight, a vegetable starch paste in a proportion of 28-47 percent by weight, liquid non-particulate PVA (polyvinyl alcohol) in a proportion of 47-65 percent by weight, and active carbon and fiber in a proportion of 0.3-180 percent by weight of all of said catalyzers, PVA and starch paste.
